Running this app fails with default OS config on Mac (Too many open files)

[timja]

A huge number of stacktraces with:

java -verbose:gc -jar ../../pipeline-steps-doc-generator/target/pipeline-steps-doc-generator-1.0-SNAPSHOT-bin/pipeline-steps-doc-generator-1.0-SNAPSHOT.jar

I can try fiddle with open file count but ideally this should work out of the box
